Posted April 7, 20196 yr I have recently began to learn to mod using Forge. I am in the process of learning about dimension travel and I ran into a problem with the code I picked out of MCJTY's dimension tutorial. I am having trouble finding out how to make the code I have work. There seems to be a bit of knowledge I have missed as I don't understand why I am unable to cast the player to a server instance. Any insight and on why this error and crash is is happening will help tremendously. My two main files for the staff that has a right-click event that triggers the teleportation and the teleportation class are in my pastebin below. ItemStaff.java https://pastebin.com/Xx9SN6xx DimTeleporter.java Error on line 43 https://pastebin.com/cqxCgaF8 Here is the CrashLog crash-2019-04-07_15.14.56-client.txt Edited April 8, 20196 yr by CrashDbo
April 7, 20196 yr EntityPlayerSP is not EntityPlayerMP. You cannot cast from one to another. if (player.world.isRemote) { EntityPlayerMP entityPlayerMP = (EntityPlayerMP) player; //Game crashes here can't cast EntityPlayerSP to EntityPlayerMP The if statement here will only be true on the client side, thus the player is SP, not MP. Are you sure you didn't meant: if (!player.world.isRemote) ? Edited April 8, 20196 yr by DavidM Some tips: Spoiler Modder Support: Spoiler 1. Do not follow tutorials on YouTube, especially TechnoVision (previously called Loremaster) and HarryTalks, due to their promotion of bad practice and usage of outdated code. 2. Always post your code. 3. Never copy and paste code. You won't learn anything from doing that. 4. Quote Programming via Eclipse's hotfixes will get you nowhere 5. Learn to use your IDE, especially the debugger. 6. Quote The "picture that's worth 1000 words" only works if there's an obvious problem or a freehand red circle around it. Support & Bug Reports: Spoiler 1. Read the EAQ before asking for help. Remember to provide the appropriate log(s). 2. Versions below 1.11 are no longer supported due to their age. Update to a modern version of Minecraft to receive support.
April 8, 20196 yr Author This solved the issue. I must have misunderstood what isRemote is. Thank you for the response. Definitely need to do more research.
April 8, 20196 yr 1 hour ago, CrashDbo said: I must have misunderstood what isRemote is. In simple words, World#isRemote returns true on the logical client side and false on the logical server side. In your case, you want the code to run on the server side, thus you should check if World#isRemote is false.
